. e it known that I, ALFRED L. SCHELLHAM- I MER, a citizen of the United States, residing at Warren, in the countyof Warren and State of Pennsylvania, have invented'certain new and;

usefullmprovements in Oil-Bailing Devices;- and I do herebydeclare the followingto be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertai-ns to make and use the same.

My invention relatesto certain. improvements in bailers for oil-wellsfor bailing oil;

' and it consists in the novelffeatures hereinafter described, reference being had to the accompanying drawings, which illustrate one form in whichII have contemplated embodying my invention, and said invention is fully claims.

disclosed in'the following descriptionand Referring t0 the drawings, Figure 1' represents. abailer provided "with my improved 3 l the main casing for cleaning and other purposes and which is less apt to get outof order valve construction. section showing the valve on its seat, and Fig. 3 is a Vertical cross-section showing the valve raised. Fig. 4: is a transverse sectional view of a modified form of bailer-casing.

, Theobject' of my invention is to providea valve for bailers to be usedin Oil-wellsfor bailing oil which is readily removable from by reason of becoming dented by the main' casing coming'in contact with the sides of the well and also to prevent the valve becoming inoperative from sediment settling on the valve-seat.

A'represents the main casing of 1m proved bailer, cylindrical in form and is pro.

videdwith an inside reinforcing-ring-B at its lower extremity, preferably united thereto the valve-seat C. The upper portion of this Fig. 2 is a vertical crossforcing-ring B.

reinforcing ring is tapered outwardly, as

shown in'the drawings, for reasons'he'rein- "after mentioned.

A valve-seat C, adapted tofit the opening in the reinforc'ing-ringB, is provided-having an enlarged portion 0, shouldered,"as at. 0, and

adapted to retain said valve in placebyrneans of machine-bolts o 0 passing through openinto' said reinforcing-ring. It is obvious-that other means may be used for securing the valveseat in the reinforcing-ringas, foreX- ample, the said valve-seat may be -screwthreaded to engage screw-threads provided on the insideof the reinforcing-ring. Onthe enlarged portion 0 are formed two down:-

wardlyextending projections'or legs .0 0

which serve as supports for the bailerand also allow' the oil to pass out.

- i'ngs 'in said enlarged portion 0 and screwed The valve occupies the central opening in the valve-seat and consists of awasher d, made of leather or other suitablernaterial, held 'in' place on the centering device d by means of the retaining-flange dand nuts d? and '05, adapted to engage the stein-E. The

centering device comprises a hollow funnel:

shaped -float (Z secured to the valve-stem by welding or soldering, and my object-in using thisform'of device is to. afford a-light' 'construction to allow the oil to pass infreely and prevent it from gasing or foaming. The stem 'E. is made of suflicient lengthtopermit the -d are ofno greater diameter than the width of the valve-seat, which construction will per-.-

mit the valve-seat,with the valve,to be slipped out upon the removal of the machine-bolts c 0" and repaired without removing the rein- It will be seen from the drawings that the valve-seat is extended upward above the point where the tapering of the reinforcing-ring B begins, which forms a sediment-trap, and this keeps the valve-seat clear.

This bailing device is adapted, primarily, for bailing oil from wells of low capacity when pumping would be inconvenient or expensive. It is therefore very important that the valve should be very light, so as to open as soon as the lower end of the bailer strikes the oil, and thereby permit the oil to flow into the casing. Hence the valve is provided with the hollow body or float d. In using these devices the bailer is raised and lowered by a rope passing over a sheave in the derrick, and the operator will mark the rope in any eonvenient manner to prevent thebailer from being lowered to the bottom of the well, which would result inv stirring up the sand and im purities and admitting them to the casing, which would injure the quality of the oil removed from the well. When the bailer is filled with oil, it is drawn up out of the well and lowered into a barrel or other receptacle, when the valve-stem strikes the bottom of said receptacle, opening the valve and permitting the oil to flow into said receptacle.

As a modification of my invention I sometimesform the body of the same of sheet-iron, preferably galvanized, which is provided longi-tudinally with exterior and interior grooved portions forming a crimped or corrugated body, as shown in Fig. 4, in which the body is indicated at A and the vertical corrugations at a. This construction makes the bailer much stronger and prevents it from becoming dented or bent.

What I claim, and desire to secure by Letters Patent, is

1. A bailer for removing oil from oil-wells, comprising a casing, provided at. its lower end with a valve-seat, a valve located on said seat and a fioat operatively connected to said valve to cause it to open when the lower end of the casinglenters the oil, substantially as described. 2. A bailer for removing oil from oil-wells, comprising a casing, provided at its lower end with a valve-seat, a valve located on said seat and a conical float connected to said valve and engaging said seat, to cause said valve to open, when the lower end of the casing enters the oil, and to center the valve upon its seat when the casing is drawn upward, substantially as described.

3. A bailer for removing oil from oil-w ells, comprising a casing, provided at its lower end with a valve-seat, a valve located on said seat, a hollow conical float connected to said valve, and extending-into said valve-seat, a stem connected to said valve and a securing device in said stem projecting below the lower end of the casing to limit the movement of the valve upward and to open the valve when the easing is lowered into a receptacle for oil, substantially as described.

4. A bailer comprising a casing, a reinforcing-ring, a valve-seat adapted to lit into the opening in said reinforcing-ring, means for detachably securing said valve-seat to said reinforcing-ring and a valve adapted to operate on said seat, substantially as described.

5. A bailer comprising a casing, areini'orcing-ring, a valve-seat adapted to iit into the opening in said reinforcing-ring and forming a sediment-trap between said valve-seat and said ring, and a valve adapted to operate on said seat, substantially as described.

6. A bailer comprising a casing, a reinforcing-ring, a bead on said reinforcing-ring proj ecting beyond said casing, a valve-seat adapted to it into the opening in said rein forcingring, means for detachabl y secu ring said val veseat to the under side of said reinforcingring, a valve' adapted to operate on said seat, a cone-shaped float secured to said valve and engaging said seat, a valve-stem extending below the casing and a cross-bar on said stem adapted to retain said valve in said bailer, substantially as described.

7. A bailer for removing oil from oil-wells comprising a casing,'provided at its lower end with a valve-seat and having supporting-legs extending below the bottom end of the bailer, a valve engaging said seat, a float operativcly connected with said valve, and a stem connected to said valve and extending below said legs whereby when the bailer is filled and is lowered into an oil-receptacle the stem will engage the bottom of said receptacle to open the valve and the oil will be permitted to pass out between said legs into said receptacle, substantially as described.

8. A bailerfor removing oil from oil-wells comprising a casing of sheet metal corrugated longitudinally and provided at its lower end with a valve-scat, a valve engaging said seat and a float operatively connected with said valve to cause it to open. readily when the lower end of the casing enters the oil, substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.
